Why are there no flotation device on Black Boxes for planes or make it floatable?

I'm waiting for:
"Why aren't planes able to transform if they're in trouble"
"Why can't planes become gliders if they lose their engines"
"Why aren't there escape pods on planes"
"Why can't a plane become a boat if it's gonna crash in the water"

You forgot "Does it take off from the conveyor?"

It could still sink...if it gets encased in the plane and falls to the bottom of the ocean still.

wasn't this question already answered?

The difference for that one, is that's what they effectively become when they lose engines. IIRC at the last communication the Air France flight had they had something like 100+ miles of glide time if it was just engine failure.

Cause it might not float out of the steel coffin it's encased.

Winner Winner Chicken Dinner

Except that it's aluminium, not steel.

The CVR (and FDR) are placed in the tail of the aircraft in an area where they are most likely to survive impact with another aircraft or terrain. There would be no practical way to ensure that the unit would come clear of the fuselage in a crash, and if you designed some sort of "ejector", you'd have the problem of recorders ejecting onto runways every time a pilot had a hard landing (I get to reset G-switches when CVRs shut down or ELTs are triggered by a hard landing more often than you would think). Currently they are painted Blaze Orange (usually with black stripes) to make them easy to locate in a land accident, and they are equipped with an ultrasonic locator beacon in case of a water landing. Until they establish real-time remote cockpit and data monitoring (which pilots would fight tooth and nail), this is about the practical limit.

On the news they said that the flight actually send automatic messages to the maintenance department with some issues. So it seems there are transmitters on the plane so that the airlines knows if there are issues. Now I'm not sure if the message send was just a short code for whatever the error is or a detailed message. It might be a low bandwidth connection.

Why not add wings to the box, make it fly home and just to be safe, add a white box inside the black box to record the flight of the black box.

LMAO

Fuck that. What I want to know is why we don't make PLANES out of the black box material.

Same reason they don't make cars out of it. It's too heavy, and something (preferably not people) has to absorb the force of impact in the event of a crash.

That sound flying over your head isn't a plane.

You are giving clamum a lot of credit...

What's the hurdle that is preventing them from revising the bb and make it transmit the data before it hits the ground/water? We've got satellites every where.

The data rate would be high. Lots of data is recorded from many sensors in real time on a modern airliner. Plus you also have the CVR data to transmit. The cost is going to be high.

That's why I suggested a burst transmission when certain conditions are met.

It's like 9/11 conspiracies, some questions never die, even when there is nothing left to argue about.
